The Secrets of A/C Systems: Common Terms Explained
MERV
MERV stands for Minimum Efficiency Reporting Value. It is a rating system used to measure the effectiveness of air filters in removing airborne particles from 0.3 to 10 microns in size, such as dust mites, pollen, mold spores, and pet dander. The higher the MERV rating, the more effective the filter is at trapping particulates. MERV ratings range from 1-16 with 16 being the highest efficiency rating.
Energy Star
Energy Star is a certification program that helps consumers identify energy-efficient products. This includes air conditioners and other HVAC systems that are designed to be more efficient than standard models. Energy Star certified products use less energy, reduce operating costs, and help protect the environment by reducing greenhouse gas emissions.
Refrigerant
Refrigerant is a fluid used in air conditioning systems to transfer heat between two spaces or objects. It works by absorbing heat from one area and releasing it into another area. Refrigerants are typically made up of hydrofluorocarbon (HFC) compounds which have no ozone depletion potential (ODP).
Coil
The coil is an important component in an air conditioning system because it helps cool the air before it is distributed throughout a space. An evaporator coil absorbs heat from indoor air while a condenser coil releases heat outside of a building. Both coils are filled with refrigerant and connected to each other via tubing or piping.
Damper
A damper is a device that is used to regulate airflow within an HVAC system. It can be manually adjusted or controlled by a thermostat to open or close depending on the desired temperature setting. The damper helps ensure that only the necessary amount of conditioned air is being circulated throughout a space, saving energy and money on utility bills.
MERV ratings measure air filter effectiveness; Energy Star certifies energy-efficient products; refrigerant transfers heat; coils absorb/release heat; dampers regulate airflow.
MERV
MERV stands for Minimum Efficiency Reporting Value and is used to rate the efficiency of air filters. It measures how effectively a filter can capture particles from 0.3-10 microns in size, such as dust, pollen, mold spores, and pet dander. The higher the MERV rating, the more efficient the filter is at capturing these particles. A MERV rating of 8-13 is considered good for residential use, while a rating of 14-16 is better suited for commercial settings. Higher ratings are also available but they require special equipment and are not typically used in residential homes. When selecting an air filter for your home or business, it’s important to consider both the MERV rating and the cost of replacement filters to ensure you get the best value for your money.
Energy Star
Energy Star is a voluntary program created by the Environmental Protection Agency (EPA) that helps businesses and individuals save money and reduce greenhouse gas emissions by using energy-efficient products and practices. It is used to identify electronic products, such as air conditioners, that are more efficient than their peers. An Energy Star certified air conditioner must meet strict standards for efficiency set by the EPA. These standards are based on the amount of energy consumed to cool a certain area, as well as other factors like noise levels and durability.
In order to become Energy Star certified, an air conditioner must have an energy efficiency rating of at least 14 SEER (seasonal energy efficiency ratio). This means that it will use less energy to cool a given space than older models with lower ratings. Additionally, Energy Star certified air conditioners must also meet minimum requirements for sound levels and durability.
The benefits of using an Energy Star certified air conditioner include lower electricity bills, improved indoor air quality, reduced greenhouse gas emissions, and greater comfort due to quieter operation. Furthermore, many utility companies offer rebates for purchasing an Energy Star certified unit in order to encourage customers to choose more efficient products.
Refrigerant
Refrigerant is a fluid used in air conditioning systems to transfer heat from the inside of a building to the outside. It works by absorbing heat energy from inside and releasing it outside through the process of evaporation and condensation. The most common refrigerants used in air conditioners are R-22, R-410A, and R-134A.
R-22 is an ozone depleting hydrochlorofluorocarbon (HCFC) refrigerant that has been used in air conditioners since the 1980s. Due to its damaging effect on the environment, production of R-22 was phased out in 2020 and will be completely banned by 2030.
R-410A is a non-ozone depleting hydrofluorocarbon (HFC) refrigerant that has become increasingly popular in recent years due to its eco-friendly properties. It is more efficient than R-22 and can be used with newer air conditioners without any modifications.
R-134A is another HFC refrigerant that has been widely used since the 1990s. It is not as efficient as R-410A but it does not damage the ozone layer like R-22 does.
When selecting a refrigerant for your air conditioner, it’s important to consider both environmental impact and efficiency. Professional A/C services can help you make an informed decision about which type of refrigerant best meets your needs.

Coil
The coil of an air conditioning unit is a key component and is responsible for the cooling process. It consists of two separate coils, one inside and one outside. The indoor coil is known as the evaporator coil and the outdoor coil is called the condenser coil. The evaporator coil absorbs heat from the air in your home, while the condenser coil releases heat to the outside environment.
The coils are connected by refrigerant lines that allow coolant to flow between them, allowing heat to be exchanged between indoors and outdoors. As warm air passes over the evaporator coil, it absorbs heat from the air and transfers it to the refrigerant inside. The refrigerant then flows through the condenser coil where it releases its heat energy to the outside air. This cycle continues until desired temperatures are reached inside your home or business.
Maintenance
It is important to regularly maintain your coils in order to ensure optimal performance and efficiency of your unit. This may include cleaning or replacing filters, checking for any signs of corrosion or debris buildup, and inspecting for any leaks or damage. Regular maintenance can help keep your unit running efficiently and prevent costly repairs down the road.
Safety Considerations
It is important to remember that both coils contain pressurized refrigerants which can be hazardous if not handled properly. When working with either coil, it is important to wear protective gear such as gloves, goggles, and long sleeves to protect yourself from potential injury or burns caused by contact with chemicals or hot surfaces. Additionally, make sure you always follow manufacturers instructions when working on either type of coil.
Important findings: air conditioning unit has two coils – evaporator and condenser – connected with refrigerant lines. Regular maintenance is necessary for optimal performance and safety considerations should be taken when working with the coils.
Damper
A damper is an important component of a heating, ventilation, and air conditioning (HVAC) system. It regulates the flow of air and helps keep the temperature in a room or building comfortable. Dampers are usually made from galvanized steel, aluminum, or other metals and are available in various sizes depending on the size of the HVAC unit. They can be manually or automatically operated, and they can be installed in walls, ceilings, or floors to regulate airflow.
Dampers are used to control the amount of air that is allowed into a room or area. They can also be used to prevent outside air from entering a space that needs to remain heated or cooled. For example, dampers can be used to close off unused rooms and help reduce energy costs by preventing conditioned air from entering them.
Dampers can also be used for zoning purposes, which allows different areas of a home or office building to have different temperatures. This helps conserve energy by only cooling or heating areas that need it rather than trying to maintain one temperature throughout the entire structure. It also allows people to customize their comfort levels in each area of their home or office building without having to adjust the thermostat setting for everyone else.
Finally, dampers can also be used as safety devices in hazardous environments like factories where toxic gases may be present. By controlling the airflow with dampers, these potentially dangerous gases can be contained within specific areas and not allowed to spread further into other parts of the building where people may breathe them in.
Overall, dampers are an essential part of any HVAC system as they help regulate airflow and provide energy savings while ensuring safety in hazardous environments.
